Mayor Bill Carpenter detailed past and anticipated costs of power plant lawsuits to city councilors this week.

BROCKTON – Documents provided this week to the City Council show millions of dollars in incurred and potential power plant legal fees, a confidential disclosure by Mayor Bill Carpenter that councilors say will not sway their opposition to the plant.

“It’s not going to change my mind,” Ward 3 Councilor Dennis Eaniri said. “We knew there was going to be a cost. But I’m going to weigh that against people’s health and well-being.”

City officials have been fighting the installation of a 350-megawatt, gas-fired plant proposed for Oak Hill Way since 2006, when Brockton Power resurrected a previous plan to generate electric power at the site.

Since then, developers have filed a $68 million lawsuit filed against city officials alleging civil rights and due process violations, and have fought a suit filed by local residents against the plant’s licensing. The latter case is pending before the Massachusetts Supreme Judicial Court.

The city has spent $1.2 million so far on legal and expert fees dealing with the various pieces of litigation surrounding the plant, according to the confidential documents, obtained Thursday by The Enterprise. The materials were prepared by City Solicitor Philip Nessralla and his staff.

Of the $1.2 million spent to date, $307,066 was spent on the civil rights lawsuit. Nessralla estimates that completing that single case could cost another $2 million.

The anticipated cost of that lawsuit makes up the bulk of potential future costs outlined in the documents. Another $202,250 could be spent completing litigation over an air permit for the power plant. Total costs could amount to more than $3.4 million.

Councilor-at-Large Moises Rodrigues said the costs will not sway his stance against the plant.

“It’s a bunch of nothing. It’s almost like an invoice,” Rodrigues. “I’m not convinced and I’m not going to vote for a settlement or anything like that.”

Ward 4 Councilor Paul Studenski said he is against the plant primarily because of health concerns residents have about its operation.

“I can’t change my mind,” he said. “I don’t want to see anybody die because of any decision I make.”

Opponents of the power plant said they believe Carpenter distributed the documents to the council to scare them into considering a settlement of the $68 million lawsuit against city officials. The mayor has said he is in favor of negotiating with the developers.

“The whole lawsuit is nothing but one whole settlement talk,” said Justin Kane, an organizer with Stop the Power. “It’s been installed purely as a scare tactic.”

City councilors are at the center of the debate over the power plant not only because they are defendants but also because without their approval, the plant cannot obtain the water it needs for cooling.

“Without the water this won’t happen,” said Kate Archard, a plant opponent and Water Commission member. “Maybe the strategy is to try to make the councilors believe that there is an egregious amount of pending law costs.”

Carpenter did not respond to requests for comment on the legal documents Thursday. Earlier this week the mayor said he would not discuss details because of the ongoing litigation and that he was “fulfilling a commitment” he had previously made to councilors to keep them abreast of the lawsuits.

There has been little movement on the civil rights lawsuit over the past year, according to several attorneys and clients involved in the suit.

The next court date is scheduled for July 29. Attorneys for both sides are expected to appear in U.S. District Court in Boston for a status conference.
